In Myst, the successful graphic adventure video game released by Cyan back in 1993, linking books are written by the D'Ni people using a process known simply as "the Art." The purpose of these linking books is to transport people to other worlds known to the D'Ni as Ages. Linking books play an integral part in Myst and its sequels, and now a working replica of one has been created. Not "working" in the sense that it can transport the reader to other ages, but working in the sense that the Cyan games can be played using this real-life version of the linking book.
